SFT (Simple Feedback Trainer) is an application designed to simulate the process of 'ringing out' a sound system and train the user to recognise frequencies by ear. It was designed after a discussion about the topic on alt.audio.pro.live-sound.

SFT is freeware which means it is free to download and use by anybody. However, if you use SFT in a commercial environment (i.e. for training) I would appreciate a small donation from your company. Any donations recieved will be put towards the future development of the software. Please note this is not obligatory.

Thanks

Thanks to the readers of alt.audio.pro.live-sound for encouragement and criticism, and to David J Taylor who wrote the original code used in the tone generator. Thanks also to ajv for early testing.
